IMPROVEMENT IN CARDlNG-MACHINES.

Specification forming part of Letters Patent N 0. 165,7!6, dated July 20, 1875; application led June 7, 1875.

To all whom it may concern:

Be it known that we, J oHN DoBsoN and JAMES DOBSON, both of the Falls of Schuylkill, Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Machines for Carding and Drawing Wool, and we do hereby declare the following` to be a full, clear, and exact description of the same, reference being had to the annexed drawings makin g part hereof'.

Our invention consists of the combination, with a carding-cylinder and an endless apron to carry the sliver, of a pair of rolls to take the sliver of wool from the cylinder, operated by pinions or belts, and placed intermediately between the carding-cylinder and the endless carrying-apron; also, ofthe combination, with the carding-cylinder and an endless apron, of a pair of rolls operated by power applied to the end of the axes of one or more of them, and set between the cylinder and the carryingapron, and a pair of rolls similarly operated and situated at the other end of the said carrying-apron, which latter rolls draw the sliver between them and the first pair 5 also, of the combination of a carding-cylinder, an endless apron, and a pair of drawing-rolls located between them, with weighted superincumbent single rolls.

To enable others skilled in the art to make and use our invention, we will describe its construction and mode of operation.

In the drawings, Figure l is an elevation of our machine, showing the cards, trough for the endless apron, and the delivery-head. Fig. 2 is a detached perspective view of one cardingcylinder, drawing-rolls, uted roll, and part of the trough for the endless apron.

A is the carding-eylinder for cardin g the wool 5 B, the doffer-conib for taking the bat from the cylinder; C, a disk or cone, having an opening in the middle; D D', two rollers operated by geared pinions E F G and pulley I, which latter is turned by a belt from the shafting. H is a carrying single roller. J is an opening' to receive the sliver of wool to the endless carrying-apron in the trough J'. K is an end pulley to carry the apron. L IWI are weighted rollers to keep the bat or sliver down on the endless apron N, which is mounted on pulleys K and O. P is a dependent smooth apron or V plane to sustain the sliver of wool in its passage to the iirst pair of rollers, R, of the delivery-head T. R It' R" are the drawingrolls ofthe delivery-head. S is a can or box to receive the sliver at the completion of the operation. Vis atrough containing endless apron `\T.

The wool is taken in a broad bat from the cylinder A by the comb B, and passes through the cone C, which contracts it to a narrow sliver; thence to the rollers D D', which draw it from the cylinder. After passing between these rollers it passes over the tluted roller H, through opening J onto the endless apron N, and, being kept down on the apron by the rollers L M M', it is carried over the plane P to and between the rollers R R' It" into the box S. The sliver is drawn by the rollers D D', and also from these rollers by the endless apron N, also from the endless apron N at M', and along its course by the rollers R of the delivery-head, or by whatever rollers may be substituted for R. It' the delivery-head were omitted the sliver would be drawn by the rollers It" in place of rollers It, which rollers R" throw the sliver into the box S. This box, when filled, is removed for the subsequent inanipulation of the sliver in the process of converting it into yarn, and is supplanted by an# other boX. The sliver is, by these several means, thus drawn considerably before it is subjected to the actual operation of the delivery-head, and the fibers composing it are straightened out and longitudinally evenly arranged before reaching the point R". rPhus an f subse uent drawin can be eonsistentl we claim as new, and desire to secure by Letters Patent, is

l. The combination, with a carding-cylinder and an endless apron to carry the sliver, of e pair of rolls to fake-the sliver of Wool from the Cylinder, operated by pnions or belts, and placed intermediately betweenl the cardingcylinder and the endless carrying-apron, substantially as described.

2. The combination, with a cerdingfeylinder and an endless apron, of a, pair of drawingrollsset between them, and alp-air of drawingrolls situated at the other end of said carrying-apron, substantially as described.

3. VThe combination of a, earding-oylinder and au endless apron with a pair of drawingrolls situated between them, land Weighted single rolls superincumbent upon the endless aprons, substantially as described.
